If Wendell says it can't be done I'd say it can't be done. I think instead of removing the scratch you'd have to fill it first with something then polish the filler. Trying to grind it out or polish it out would only compromise the glass and give you a weak spot.

You could try something like speedy auto glass, try to find out what they use to repair car windshields but it may not be reef safe or suitable for underwater use.

I've tried using two part epoxy on glass and found it didn't stick, water got behind it and it lifted off so don't waste your money on that.

Let me know if and where you find any - I would be interested in some. I looked at Canadian tire for any glass product that contained some of that compound, but I didnt find any. I think that I put a few scratches on my new-to-me tank while cleaning it out...

Look under "lapidaries" in the yellow pages. They carry cerium oxide and many other polishing compounds for working with glass.

I have ground a few telescope mirrors in my life and use many types of grinding media for working with the glass blank. Last of which is cerium oxide, to finely polish the mirror before coating it.

You can remove the scratches. but be prepared for many hours of work. I do believe the lensing effect of grinding out scratches on the inside of the tank may disappoint as well.
